This is the promised followup from my previous posting:

How to get > 1024Cylinders/1024mb DOS Volumes

I successfully partitioned and formatted a 2.0gb (rated capacity) Fujitsu
2652SA SCSI HD to 1,745,616,896 bytes (call it 1.75 gb).  I partitioned and
formatted it under OS/2 ver 2.0, and then rebooted the machine under DOS. 
I have 2 of these disks on the machine.  Drive E: was partitioned and
formatted (as a FAT filesystem) under OS/2 ver 2.0, and DOS chkdsk running
under DOS alone reported:

1,745,616,896 bytes

32768 bytes per allocation uint
53272 total allocation units on disk

Drive F: was partitioned and formatted under DOS alone.  Chkdsk reports, as
expected:

1,073,430,528 bytes

16384 bytes per allocation unit
65517 total allocation units on disk

So you see, it works.

There is one correction to my previous posting.  One must actually install
OS/2 in order to format the drive as a FAT file-system.  You don't have to
install it on that drive, but you do need to have OS/2 installed in order
to run the OS/2 format program.  If someone finds a way around that, I'd
like to know, but I do like OS/2, so I don't need to worry about it.  I
just attach disks to my computer, partition and format them for DOS folks,
and then give them the drives back.
